[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Figure 1 、 Figure 3 and Figure 4 As shown, the utility model provides a lightning protection monitoring box for equipment, comprising a shell 1, a lightning protection box 2 is provided in the inner cavity of the shell 1, and a movable mechanism 3 is installed inside the shell 1;

[0024] The movable mechanism 3 includes a storage rack 31 and a fixed plate 39. The top end of one side of the fixed plate 39 is rotatably connected to the first transmission rod 34. The top end of the first transmission rod 34 is rotatably connected to the side wall of the storage rack 31. The outer surface of the top end of the first transmission rod 34 is fixedly connected to the first linkage rod 33. The top end of the side wall of the fixed plate 39 is rotatably connected to the sleeve 35. The inner side of the sleeve 35 is slidably connected to the movable rod 38. One end of the movable rod 38 is rotatably connected to the second linkage rod 36. The outer surface of one end of the second linkage rod 36 is fixedly connected to the second transmission rod 37. The top end of the second transmission rod 37 is rotatably connected to the side wall of the storage rack 31, and the second linkage rod 36 is rotatably connected to the side wall of the fixed plate 39.

[0025] The following details the specific configuration and function of this embodiment. When the pull rod 32 is pulled, it connects to the first linkage rod 33, causing the first linkage rod 33 to move synchronously, thereby driving the first transmission rod 34 to begin moving. At this point, the first transmission rod 34 begins to rotate around its bottom end, acting as the center of rotation. This causes the storage rack 31 to move out of the housing 1, while the height of the storage rack 31 decreases. The movement of the storage rack 31 is not only linear but also accompanied by changes in height, allowing it to adapt to different operational requirements.

[0026] During this process, the second transmission rod 37 plays a crucial role. It swings around its connection point with the second linkage rod 36. This swinging motion effectively drives the auxiliary storage rack 31. The movement of the auxiliary storage rack 31 ensures smooth placement and removal of equipment, enhancing the operational flexibility of the rack 31.

[0027] Simultaneously, as the storage rack 31 moves, the second linkage rod 36 also moves, connecting to the movable rod 38 through it, causing the movable rod 38 to move along a predetermined trajectory within the sleeve 35. The movement of the movable rod 38 compresses the spring 351 within the sleeve 35. This compression not only changes the shape of the spring 351 but also provides the necessary elastic reserve for the subsequent reset action.

[0028] After the operation is complete, when resetting is required, the system initiates reverse motion by pulling the pull rod 32 in the opposite direction. At this point, the spring 351 within the sleeve 35 gradually returns to its original position through its own elastic restoring force. This restoring force not only allows the auxiliary storage rack 31 to be smoothly reset to its original position, but also, through the rebound action of the spring 351, helps the rack 31 retract the internal device into the housing 1. The resetting of the rack 31 not only protects the device from damage from the external environment but also facilitates subsequent removal or maintenance of the device, further improving the safety and operational efficiency of the device.

[0029] Example 2: Figure 1 and Figure 2As shown, a spring 351 is provided on the inner side of the sleeve 35, and one end of the spring 351 is in contact with the movable rod 38. A pull rod 32 is provided on one side of the storage rack 31, and both ends of the pull rod 32 are fixedly connected to the first linkage rod 33. A 485 communication interface 21 and a lightning arrester remote control signal interface 22 are provided at the bottom end of the inner side of the lightning protection box 2. A DC voltage monitoring interface 23 and an AC voltage monitoring interface 24 are provided on one side of the lightning arrester remote control signal interface 22, and a resistor divider 26 is installed on the inner wall of the lightning protection box 2. A coil collection interface 25 is installed on one side of the inner wall of the lightning protection box 2, and a box door 28 is rotatably connected to one side of the lightning protection box 2. An audible and visual alarm indicator 27 is installed in the center of the box door 28.

[0030] The effect achieved by the entire embodiment is that the coil acquisition interface 25 is connected to the Rogowski coil, and the non-contact induction principle of the Rogowski coil is used to monitor the induced current in the ground wire of the equipment. The Rogowski coil can effectively detect current fluctuations caused by lightning strikes or induced lightning, thereby promptly identifying the risk of lightning strikes or electromagnetic interference that electrical equipment may suffer. When a lightning current is sensed, the system will immediately activate the protection mechanism and issue an alarm to ensure that the equipment is protected from lightning damage. The resistor divider 26 is used to collect the power supply current of the equipment. Through precise voltage division, the resistor divider 26 can accurately measure the current consumed during the operation of the equipment and convert it into a monitorable signal to transmit to the system. This signal can help determine the current load status of the equipment. If a current overload or abnormal fluctuation occurs, the system can issue an alarm in time to avoid equipment failure due to unstable current. DC voltage monitoring interface 23 and AC voltage monitoring interface 24.

[0031] The device is equipped with a DC voltage monitoring interface 23 and an AC voltage monitoring interface 24, which monitor the device's DC and AC voltages, respectively. These interfaces not only collect real-time voltage data during device operation but also analyze voltage fluctuations to determine whether the device's power supply system is functioning properly. For example, if the voltage is too low, too high, or unstable, the system can promptly identify and issue a warning signal, preventing power failures from impacting normal device operation.

[0032] To ensure safety during on-site operation, the equipment is equipped with an audible and visual alarm indicator 27 on one side of the door 28. When the equipment detects abnormal current or voltage, or a lightning protection system failure, the audible and visual alarm system immediately triggers, emitting strong visual and audible signals to alert operators to potential electrical issues. This indicator effectively draws attention in noisy or complex environments, ensuring that personnel can take timely action to prevent equipment damage or safety incidents.

[0033] In addition to local alarm functionality, the device is equipped with a 485 communication interface 21 for exchanging data with external devices or monitoring systems. Through this interface, the device can transmit real-time monitoring data, alarm information, and device status to a remote control platform or monitoring center. This interface supports remote data collection and analysis, facilitating centralized management and monitoring of the device. Whether conducting regular inspections or in the event of an emergency, managers can remotely monitor device status and take appropriate countermeasures, improving device management efficiency and responsiveness.

[0034] The device also supports external data output via the 485 communication interface 21, capable of transmitting operational data, fault alarms, and real-time current and voltage information to a cloud platform or remote monitoring center. This capability extends device monitoring beyond local locations, allowing managers to conduct real-time monitoring and management from anywhere via a remote terminal. This ensures that any anomalies in device operation are quickly identified and addressed, improving operational efficiency and reliability.

[0035] By analyzing the device's power supply voltage and current, the system accurately determines the device's power supply information. Whether powered by DC or AC, the device can determine whether its power supply is within normal range based on real-time voltage and current data. If voltage instability, excessive current, or insufficient current occur, the system automatically issues an alarm based on pre-set thresholds, helping operators promptly adjust or correct the power supply issue, thereby ensuring safe operation of the device.

[0036] The device's operating principle and usage are as follows: Pulling the pull rod 32 activates the first linkage rod 33, thereby initiating movement of the first transmission rod 34. During this process, the first transmission rod 34 rotates about its bottom end, causing the storage rack 31 to move out of the housing 1 and descend. During this process, the second transmission rod 37 synergizes with the auxiliary storage rack 31 by swinging about the connection point between the second transmission rod 37 and the second linkage rod 36, thereby driving the movement of the auxiliary storage rack 31. As the storage rack 31 moves, the second linkage rod 36 also moves, driving the movable rod 38 to move within the sleeve 35, squeezing the spring 351 and causing it to compress.

[0037] When resetting, the pull rod 32 is pulled in the opposite direction, and the spring 351 inside the sleeve 35 uses its own elasticity to return to its original position, thereby assisting the storage rack 31 to reset and store the equipment inside the storage rack 31. This not only helps to protect the equipment, but also makes it easier to take out the equipment for maintenance.

[0038] The coil acquisition interface 25 is connected to a Rogowski coil, which collects the induced current in the device's ground wire through the Rogowski coil to monitor the device for lightning strikes or induced lightning. Simultaneously, the device's power supply current is collected through a resistor divider 26. The device also features a DC voltage monitoring interface 23 and an AC voltage monitoring interface 24, capable of collecting two types of current signals. By analyzing the device's power supply voltage, the device's power supply information can be determined. An audible and visual alarm indicator 27 is installed on one side of the box door 28. When the device detects a lightning protection issue, the monitoring box can issue an alarm signal. The device also features a 485 communication interface 21, which, in addition to providing an alarm function, can also output remote data and support remote monitoring.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
